While this Sunday's game in Orchard Park will be the 10th meeting between the Buffalo Bills and the Kansas City Chiefs, with Patrick Mahomes and Josh Allen under center, the rivalry is one of the best in the NFL. The Bills are 4-5 in this competition, hoping to secure the win.
While both teams tend to play with a chip on their shoulders, they are both fighting for their playoff lives and really need to win this one on Sunday.
